  i just got my yorkie 2 wks ago and she is a teacup size so she won't be any heavier than probably 4 lbs. when i took her to the vet, the first thing i asked since i knew yorkies are prone to CT was what type of anesthesia they use and what the process entailed of putting a pet under. 
i specified that i was looking for a vet who uses isoflurane since its safest for dogs this small and she did use that. she also said that she would have to intubate when they go under (when they insert the tube through the trachea) which i immediately asked if it was necessary since its so risky but she did say that she had tubes of all sizes including sizes that are used on kittens smaller than my puppy which only makes me imagine how tiny they are since my puppy is barely 2 lbs. hope this helps and i'm so sorry about your little guy! 
there 
are small tubes out there and the right anesthesia!
